CWP Webcast 8: Methods to Address Pollution Sources from Municipal Practices (In-Person Viewing) 

We are bringing back in-person webcast viewing in 2023!

Registration will be capped to the first 25 to help ensure social distancing. Currently, masks are welcome, but not required in our office. If you prefer to view the webcast remotely and are not a Coalition Member, contact Brooke at bfrusher@franklinswcd.org to discuss your options.

Presentation Information

Andy Erickson, PhD, PE, St. Anthony Falls Laboratory, University of Minnesota | Biofilters can be used to treat stormwater runoff from urban landscapes, but some media used in biofilters can release phosphate or limit plant growth. As such, stormwater professionals struggle to choose media for biofilters. This presentation will share the final performance results from four rainy seasons of simulated runoff events through biofiltration mesocosms, including road-salt-laden events to simulate spring snowmelt in cold climates like MN. With the information from this study, stormwater practitioners will be able to design better biofiltration practices that capture phosphorus and support healthy vegetation.

Doug Klimbal, Bolton & Menk, Inc. | Pollutant impact reduction often leans heavily on treatment practices which capture and retain contaminants. This is a viable approach for many stormwater quality parameters, especially those which are chemically reactive. Chloride is a notable exception. Our industry lacks an approach for chloride removal. Instead, source reduction has become the key method for addressing chloride as a local and regional water quality concern. This portion of the webcast will highlight aspects of successful chloride source reduction initiatives in municipal settings, including training for operations and maintenance personnel, encouraging community-wide public buy-in, facilitating more advanced maintenance practices, and even implementing source reduction by design.
